Figure 5From: Inferring nonneutral evolution from contrasting patterns of polymorphisms and divergences in different protein coding regions of enterovirus 71 circulating in Taiwan during 1998-2003Phylogenetic tree for the VP1 region of enterovirus (EV) 71 isolates in Taiwan between 1998 and 2003 and from surrounding areas between the 1990 s and 2003. Numbers close to the branches are from 1000 bootstrap replicates (%). The two digits at the end of a sequence indicate the year of isolation.
